net/mlx5: Expose uar access and odp page fault counters
Add three counters to vnic health reporter:
bar_uar_access, odp_local_triggered_page_fault, and
odp_remote_triggered_page_fault.
- bar_uar_access
number of WRITE or READ access operations to the UAR on the PCIe
BAR.
- odp_local_triggered_page_fault
number of locally-triggered page-faults due to ODP.
- odp_remote_triggered_page_fault
number of remotly-triggered page-faults due to ODP.
Example access:
$ devlink health diagnose pci/0000:08:00.0 reporter vnic
vNIC env counters:
total_error_queues: 0 send_queue_priority_update_flow: 0
comp_eq_overrun: 0 async_eq_overrun: 0 cq_overrun: 0
invalid_command: 0 quota_exceeded_command: 0
nic_receive_steering_discard: 0 icm_consumption: 1032
bar_uar_access: 1279 odp_local_triggered_page_fault: 20
odp_remote_triggered_page_fault: 34
